MINE CAR.

Application led December 23, 1924. Serial No. 757,659.

Reference is had to the accompan ing drawings which illustrate thepreferred orin claims will occur to persons skilled in the art.

In said drawings:

An object of this invention is to provlde a mine car having an improvedbody p ortion' including an intermediate ysection formed oflongitudinally disposed floor boards vand side sectionsy formed of sheetmetal and connected with the intermediate section in an improved manner.

Another object of the invention is to so connect the side sections withthe intermediate section that they will be very securely held in placeand firmly braced agains downward movement.

Another obpect of the invention is to so construct the side sectionsthat portions of these sections intermediate the length of the car maybe arched upwardly and provide external pockets open at their lower andouter sides and adapted to receive the upper portions of the wheels ofthe car.

Another object of the invention is to so form these pockets that brakestructure may be suspended intermediate the ends of the pockets andbetween the wheels of the c ar.

This improved mine car is provided wlth a body portion having side walls1, end walls 2 and a bottom indicated in general by the numeral 3. ThisVbottom 3 is provided with an intermediate section formed oflongitudinally disposed floor boards 4 and side sections which areformed of sheet metal. length than the body portion and have their endportions extending beyond the end walls and covered by metal jackets orbumpers 6 which straddle the extended ends of the boards 4, as shown inFig. 1. Fasteners 7 pass through the boards 4 and upper and lowerflanges of the bumpers so that the bumpers will be securely held inplace. The extended ends of the center board 4 and the flanges of thebumpers are also' provided with openings toreceive the coupling pins 8which pass through the eyes at the ends of the draw har 9. This draw bar9 extends longitudinally of the car intermediate the width of the centerboard 4 and has it-s end portions extended upwardly and then outwardlythrough the end walls in spaced relation above the extended ends of thecenter board. The pins 8 are adapted to pass through mine car couplersof a conventional construction and may be secured against accidentalupward movement when in place. At one end of the car there has beenshown a latch for retaining the coupling in in place and this latch isillustrated in ig. 6.

Referring to this ligure and to Fig. 1, it will' be seen that the latch10 is in the form of a strip which is pivotally connected with the endwall by means of a pin or bolt 11 which asses through the end wall andthrough a racket 12. The lower end portion of the latch forming strip isbent to provide an arm 13 which extends outwardly from the end wall ofthe car body and is of such length that it may be positioned between thecollar 14 and head 15 ofthe pin. Therefore the pin will be securely heldin place until the latch is swung out of an operative position.-

Each of the side sections 5 of the body is formed of metallic plates l16which have their inner side portions extending in overlapping relationto the intermediate section, as shown in Figs. 4 and 5, and have theirouter side portions bent upwardly to provide flanges 17 which aresecured to the lower ed e portions of the side walls 1 by means ofrivets 18. The metallic plates which form the wheel hood portions of theside sections intermediate the length of the car body are stamped toprovide bowed por- The iioor boards 4 are of greater tions 19 whichextend upwardly into the car body and provide external pockets 20 whichare open at their outer and lower sides. Of course the intermediateportions of the side walls have their lower edge portions removed atthis point to correspond to the pocket and permit ready access to thewheels so that the flanges of the plates forming the intermediate orwheel hood portions of the side sections may be secured to the sidewalls, as shown in Fig. 5. In order to firmly connect the side floorsections with the intermediate floor section there have been providedZ-bars 21 which extend along the side edge faces of the intermediatesection and have their upper flanges 22 secured to the under faces ofthe side sections by rivets 23 and their lower flanges 24 extendingbeneath the side portions of the intermediate section and secured bybolts or other suitable fasteners 25 which extend through theintermediate section and through the overlapped inner side portions ofthe side sections. This is clearly shown in Figs. 4 and 5 and referringto these figures, it will be seen that the side sections will be verysecurely attached to the intermediate section. Therehas also beenprovided yokes26 which have their bridge portions extending transverselybeneath the body and their arms 27 yextending upwardly along the outerfaces of the side walls and constituting'posts which will be secured tothe sidewalls by the rivets 28. The intermediate portions of the bridgeportions of these yokes are secured to the intermediate floor sectionsby bolts or other fasteners 29 and the end portions of these bridgeportions are bent at an upward incline, as shown at 30, and thenextended outwardly along the under faces of the side sections of theflooring and secured by rivets 31. The floor boards and metal platesforming the flooring of this improved mine car body will therefore bevery firmly connected with each other and braced against movement out ofthe desired position. The upper edge portions of the side walls are bentoutwardly and downwardly to provide depending stifi'ening flanges 32which overlap the upper ends of the arms or posts 27 and serve to assistin retaining these posts in the proper position and also serve .toprovide the -upper edges of the walls with rounded edges. The upper edgeportions of the end walls are also bent over to provide these walls withrounded edges but in the preferred form the end walls have their upperedge portions turned inwardly and downwardly instead of outwardly.

The axles 33 extend beneath the body intermediate its length and inspaced relation to each other and have their end portions rotatably inounted in bearings or journal boxes 34 which are secured to theintermediate section of the flooring or bottom of the car body in theusual manner. The end portions of the axles extend outwardly beyond. theside edges of the intermediate floor section but terminate short of thevvertical plane of the side walls. The Wheels 35 are mounted upon theseextended end portions of the axles and the-se wheels have their upperportions extend ing into the end portions vof the pockets 20. Brakeshoes 36 are provided between the wheels at each side of the car andthese shoes are suspended by hanger strips 37 which are pivot-allyconnected with bracket strips 38. These bracket strips 38 are. disposedintermediate the length of the pocket 20 in spaced relation to eachother and are secured by rivets or other suitable fasteners. Links 39are pivotally connected with the brake shoes and extend towards eachother with their adjacent ends pivotally connected with the upper end ofa strip 40 which is pivotally connected with the outer end portion ofthe arm 41 of the operating shaft 42. One of these shafts 42 will beprovided at each side of the car and these shafts extend beyond the endwall and are provided with upwardly extending lever arms 43 which areconnected with the operating lever 44 by links 45. The links 45 areconnected with the lever 44 above and below the pivot point 46 of thelever 44 and therefore when the operating lever is moved the levers 43of the two shafts will both be swung either inwardly or outwardly at thesame time. This will cause both of the shafts to be rotated to eitherapply or` release the brakes.

The Z-bar side sills 21 which are shown and described herein may extendsubstantially the length of the car body and when they rest on thejournal boxes 34 serve as additional supporting means for such carbody.I An additional support is provided by the flange connection of theside floor sections 16 and 19 to the side wall of the car body and theconnection of the yoke members or belts 26 as best illustrated inFigures 4 and 5.

It will therefore be seen that the car body is so constructed that thewheels and the brake structure between the wheels at each side of thecar may be mounted below the bottom or flooring of the car body withoutthe wheels or brake structure extending beyond the sides of the carbody.

A feature of the invention con'lprises the floor portions formed asillustrated in Fig. 3 in which four metallic corner floor sheets 16 areprovided overlapping the upper flanges of the Z-shaped side sills asshown in Figs. 4 and 5y, and the twin wheel hoods or intermediatelongitudinal metallic floor portions 19 are each formed of a singlesheet of metal lapping the corner sheet 16 and riveted thereto.

Such intermediate floor portions 19 overlap the sills 21 and wood floorportions and are bent upwardly as illustrated in Figs. 1,

3 and 4 to form twin wheel hoods, that is,l

hoods each capable of covering and partly enclosing a pair of supportingWheels and brake rigging hereinbefore described, which brake rigging ispositioned within these twin wheel hoods and relatively between the sidewalls of the car, between the wheels at each side, thus utilizing all ofthe space covered by the twin wheel hoods to the best advantage.
